Using Global Content with the Foundation theme
Global Content works great with Foundation theme, you even do not have to switch the theme when using it, since the Foundation theme is a blank theme as well (although, if you are using any other theme, do NOT use the Foundation theme as a blank theme for it with Global Content)
We have been asked a lot if you need to include the Site Styles stack on the content page you are importing with Global Content. The answer to this is no, in fact, it is better to not include Site Styles in the content page. We understand to setup the page, you will need to add it, but we suggest you delete it right before publishing the page.
Other than that, you should have no issues using Global Content with Foundation.
Now go forth and make your websites great!
